I happened to be in a situation where I can't even fully flush the postfix
queue without having
Dspam to segfault.
I end up installing dspam-dbg and gdb and attach to the process [I wasn't able
to run the process
without the init-script].
Here is a stack trace, but sadly libdspam7-drv-hash does not provide debug
symbols.
